Specification of Letters Patent.

Patented Jan. 30,1912.

Application filed. June 23, 1910. Serial No. 568,463.

Leicester, Leicestershire, England, have invented certam Improvements in Pounding- Up, Leveling, or Smoothing Rolls, of which the following description,

in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to tools for use in pounding-up, leveling, or smoothing and finishing the parts of boots and shoes, and in particular to certain improvements in the construction 'of' such tools which adapts them to perform more efficiently than heretofore the operation of re-forming the bottoms of turn shoes.

The invention comprises as an important feature a rotatory tool composed of a body portion and a plurality of beating and smoothing members pivoted to the body and having their work-engaging faces so curved as to form collectively a cylindricalroll.

-In its preferred form, the beating and smoothing members are pivotally connected with abutments carried by the body of the roll and their work-engaging portions are so shaped and arranged that they will present a cylindrical surface only when the members have been forced inward by contact with the work so as to engage the abutments. As the roll rotates the beating and smoothing members are caused to swing outwardly by the centrifugal force 'due to the rotation of the roll, and when the work i is moved against the members they will yield, more or less, in proportion to the amount of pressure imparted to them by the work, and will likewise act upon the vwork with a pounding and reducing force which will solidify its surface and impart i r a finish thereto, according to such pressure.

a predetermined pounding,

By this means,

action may be'obleveling, and finishing tained upon any work presented to the roll,

and as the degree of solidification of the work will be dependent upon its pressure against the movable roll members, the operator may vary the same by merely moving the work appropriately toward or from said members.

' Preferably, the pivoted members referred to are so disposed around the roll body as to provide spaces between their adjacent edges, so that said members collectively form a ribbed cylindrical roll.

Other features of the invention, includingimportant details of construction and comblnations of parts, will be hereinafter more partlcularly described and claimed.

In the drawings: Figure 1 is a side eleva tion of a roll embodying the presentinvention, together with its operating shaft, and a shoe-lronlng or shaping tool associated therewith, several of the beating members of the roll being omitted with a view to clearness of illustration; Fig. 2 is a view in cross-section on' the line 00-00, Fig. 1, and Fig. 3 is a detail view showing, in inverted plamlcertain parts which do not appear in A suitable support or pedestal 1, sustains a yoke 4, which is provided with trunnions 8 to pivotally support a sleeve 3, constituting a bearing for the driving shaft 2. The

shaft 2 is shown as having on one side of the sleeve a fast pulley 10 to receive power through a belt from any suitable source. On the other side of the bearing 3 a sleeve 5 surrounds the shaft and is secured thereto by pins 6, or any other suitable means, said 7 sleeve having at its ends, the flanges 7 which constitute abutments for the work engaging members 9 of the roll. The work engaging members are shown as being in the form of bars having inwardly extending I lugs 15 which fit against the inner opposed surfaces of the abutments 7, to which they are pivotally connected by pins 13 whose ends pass through holes in the lugs 15 and enter sockets l7 formedin the abutments 7. 1

The members 9 are also provided with end portions 11 extending beyond the lugs 15 and overlapping the perimeters of the abutments upon which said end portions rest when the members 9 occupy their outermost positions. Each pivot pin 15 is located below the leading edge 19 of the member 9 with which it is associated so that during the rotation of the roll in the direction indicated by the arrow in Fig. 2 the'following edge 21 of each member will be raised from the abutments by centrifugal force and the members will engage the work when the same is presented to the roll; After the members have engaged the work they will I 1, and these cutaway portions form stops to limit the extent of the outward movenfents of said members, In order to facilitate the assembling of theparts constituting the roll, the body part 5 may be formed in two semi-cylindrical portions each of which may carry one of the flanges or abutments 7, and said portions be secured to the shaft 2 by the pins 6, or other suitable means.

In connection with the beating and finishing roll I have shown an ironing tool 20,

which may be advantageously employed for ironing and. smoothing outthe upper of a shoe, to remove the wrinkles and to impart a finish to certain portions of the shoe, as for instance along the shank and in the crease formed between the upper andsole, where, by reason of its shape, the beating tool is not adapted for operation. The tool 20 is shown as being curved appropriately for fitting the convex portions of the upper, and terminates at the rear in a relatively thin edge 200 which is shaped to enter the rand crease, or the crease formed between the upper and sole at the shank. The inner end of the ironing tool is supported from the flange 7 of the beater roll nearest the right hand end of the shaft 2, as seen in Fig. 1. A collar 22, secured tovthe shaft bearing 3,

i supports through a pivot 23 one end of a bent rod 24, and the opposite end of this rod is attached to a bracket 26 by a screw 27 The upper part of the bracket 26 is arranged to fit against the outer end of the tool 20, and is perforated to receive a rod 28. The tool 20 is provided with a cavity to receive two friction members 30 which are formed with wedge-shaped engaging faces 31. A coil spring 33 is located in a recess between the friction members 30, and has its inner end attached to one of said members and its outer end attached to the inner extremity of the pin 28, as shown by dotted lines in Fig. 1. The outer end portion of the pin 28 is provided with a screw thread to which is applied an adjusting nut 32,,which bears against the bracket 26 and acts to control the tension of the spring 33.

Byturning the nut more or less, the friction members are caused to expand and grip the inner surface of the tool 20 to the extent desired,

I The devices just described serve to sup port the outer end of the ironing tool and particularly the friction. heatingdevices 30 which are restrained from rotation with the ironing tool 20 by the pins 35 'whichextend from the bracket 26 into the thick outer end of the lower member 30.

The novel feature of this invention which consists in an improved construction for supporting an ironing tool andheating it is not herein claimed but forms the subjectmatter of a divisional application Serial No. 618,335, filed April 1, 1911.

Having described my invention, what I claim as new and desire to secure by Let ters Patent of the United Statesis:
